Alcohol is well known agent which can damage the human tissues such as liver via stimulating lipid peroxidation and storage, denaturation of macromolecules, and inhibiting protein metabolism. On the other hand, carotenoids in addition to vitamins A, C, E and lipoic acid, play important roles in protecting these oxidative damages as well as preventing the production of free radicals. This study was carried out to elucidate the precise effects of alcohol administration into rats on the antioxidative functions of dietary carotenoids and isolated β-carotene, and to find out any parameters to uncover more detailed biochemical mechanisms of these agents. For these purposes, two different approaches were performed: 1) examination of the changes in hematological parameters (e.g., total proteins, A/G ratio, ALT/AST et. al) and statistical correlations among inter- and intragroups, 2) examination of the histopathological changes by an electron microscope. The results were analyzed and summarized as following; (1) Carrot diet for one week caused a slight increase in albumin. A/G ratio and AST levels, and a slight decrease in ALT, ALP, BUN and uric acid levels. Two-week alcohol administration following carrot diet increased total proteins, albumin A/G ratio and BUN levels. However, both groups were shown to have little significant changes in cholesterol concentrations. (2) Cheese diet for one week caused a significant increase in total proteins, albumin, AST, ALP, uric acid and total cholesterol levels, and a significant decrease in A/G ratio and glucose concentrations. However, two-week β-carotene diet following cheese intake increased total proteins albumin, A/G ratio, BUN and total cholesterol levels, whereas AST, ALT, ALP and uric acid levels were decreased. (3) Alcohol administration for one week caused an increase in AST activities and a decrease in total proteins, albumin, ALT, ALP and BUN levels. A successive β-carotene diet following alcohol administration increased total proteins, albumin, ALT, ALP and BUN levels, whereas decreased AST and uric acid levels. However, there were not significant changes in A/G ratio, glucose and total cholesterol levels in both groups. (4) β-carotene diet for one week caused a slight increase in albumin, glucose, AST and uric acid levels, and a slight decrease in ALP and BUN levels. Two-weeks alcohol administration following β-carotene diet increased albumin, glucose, BUN and total cholesterol levels, whereas decreased AST, ALT, ALP and uric acid levels. (5) Although the pathological investigation on the liver did not reveal significant changes, cheese diet group (CH-BC/1-CH) was shown to have some lipid deposits. Some results were unexpected and different from typical hematological changes shown by other researchers. Nonetheless, these results strongly suggest that the liver damage or hepatism caused by alcohol intake affects many kinds of biochemical metabolisms, which results in significant changes in many hematological parameters. In addition, dietary carotenoid and isolated β-carotene were shown to have protective roles against the biochemical changes by alcohol intake.

This study was carried out to investigate the effect of ginseng extract on ethanol metabolism and histopathological changes of liver tissues n alcohol administered rats. White rats of three groups(untreated normal control, A,B) were pretreated with ginseng extract (10ml/㎏ B.W) for 15 days, and then were given with combined ginseng extract-40% alcohol(group A) and 40% alcohol(group B) by polyethylene catheter through mouth for another 30 days. The description was based on the analysis of blood sample collected by 5 days interval. The results obtained were summarized as follow : 1. The mean concentrations of serum alcohol were significantly higher in group A and group B than those of control during total experimental periods. The mean concentrations of serum alcohol were significantly lower in group A than those of group B. 2. The activities of GOT and ADH, concentration of α₂-globulin, cholesterol and triglyceride were increased than those of group A, and the more lengthy period alcohol adminstered, the more increased change observed. But in alcohol-ginseng extract administered group A, these were significantly decreased in similar to those of normal control group. 3. The blood components which is markedly influenced by administration of ginseng extract were found in the followings : enzymatic activities such as GOT and ADH, contents of α-₂globulin and cholesterol. 4. With microscopic observation, hepatic tissues of group B were observed to have mild infiltration of lymphocytes from the feeding 10th day. However the moderate destruction of hepatic architecture, prominent ballooning degeneration and mild infiltration of lymphocytes were apparent from the feeding 20th day. But mild ballooning degeneration of hepatocytes was observed in periportal area in group A, whereas at the feeding 30th day, the mild infiltration of chronic inflammatory cell in the portal tract was less severe than that of group B. Based on these results It can be suggested that the activities of serum GOT and liver ADH which is most sensitively influenced by ginseng extract may have the parameter of the protective action against alcohol, in addition to protective action of ginseng against alcohol degradative effects.

This study was carried out to investigate the effects on the changes of the r-glutamyl transpeptidase activity of ethanol-administered white rats. There was classified into group; ethanol treated group(group A), ethanol treated group which was pretreated with ginseng extract(group B), ginseng extract treated group(group C), and ginseng extract treated group which was pretreated with ethanol(group D). White rats of four groups were treated with combined 1% ginseng extract and / or 20% ethanol for 30 days, and were measured the changes of r-GTP activity on the serum, hepatic and renal tissue sample collected at 5 days interval. Following results have been obtained. 1. The changes of serum r-GTP activity were significantly decreased in ethanol treated group B which was pretreated with ginseng extract than in ethanol treated group A. The values were highly significant at the 20th day of feeding. 2. The changes of hepatic r-GTP activity were more increased in group A and decreased in group D. The values were found significantly lowest in 10th and highest in 5th days. 3. The changes of renal r-GTP activity were more increased in group A and decreased in group D. The values were significantly highest in 10th and lowest in 20th days. Based on these results it was found that the changes of r-GTP activity between serum and hepato-renal tissue were exist and the protective action of ginseng against alcohol degradative effects was noted.

장희선 ( Hee Sun Chang ),한태영 ( Tae Young Han ),이현경 ( Hyun Kyung Lee ),손숙자 ( Sook Ja Son ) 대한피부과학회 2011 대한피부과학회지 Vol.49 No.5

Transverse leukonychia, also termed leukonychia striata, usually occurs in association with trauma, nutritional deficiencies, exposure to toxin, and various combinations of chemotherapy. It also has been reported to be associated with various systemic diseases, including acute infection, myocardial infarction, lymphoma, hepatic failure, renal failure, and systemic lupus erythematosus. A 50-year-old woman with several months` history of nail changes presented with multiple discrete transverse white bands involving the entire width of the nail plates of her fingers. According to the patient`s medical history, she had experienced fatigue, constipation, and cold intolerance for 6 months, and antithyroid antibodies were detected before noticing these nail changes. The patient was diagnosed as having an autoimmune hypothyroidism. Repeated KOH microscopic examination did not demonstrate fungal infection. We diagnosed this case as transverse leukonychia associated with hypothyroidism. This case report underlines the possible association of transverse leukonychia with hypothyroidism.

Thermoplasma acidophilum의 20S Proteasome에 의한 ATPase-활성적 단백질분해에 관한 연구

우기민,장예진,조만희,김창세,김완종,조성호,이상한 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.1

The eukaryotic 26S proteasome is an ATP/ubiquitin-dependent proteolytic complex consisting of the 20S core particle and 19S ATPase complex. However, because of its complexity and unstable properties, this study was carried out to present more simple and stable model for the ATP-activated proteolytic complex in prokaryotes which can take the place of the eukaryotic 26S proteasome. For this purpose, recombinant Thermoplasma 20S proteasome (T20S) and Methanococcus MS4, a sequence homolog of one ATPase subunit in the 19S ATPase complex, were successfully isolated from Escherichia coli (E. coli). The α and β subunits of T20S expressed in E. coli could assemble for themselves, and showed the peptide-hydrolyzing activity. Whereas both T20S and R20S (the 20S complex from rabbit skeletal muscle) had the highest peptidase activity against Suc-LLVY-AMC, a good substrate for chymotrypsin-like peptidase activity, the specific activity of T20S was slightly lower than that of R20S. In addition, several reagents such as KCI, SDS, and ovalbumin were shown to have different effects on the peptidase activities between T20S and R20S. When the ATPase activity of the purified MS4 were assayed , the Km for ATP was about 0.5 mM, and casein could stimulate the activity more than 2 fold without the change in Km. This result implicates that protein-activated ATPase may induce the conformational change of casein, and therefore suggests that MS4 ATPase may activate the proteolytic activity of the 20S proteasome via accelerating the recognition and translocation of the protein substrates.

Hwang, In-Chang,Kang, Dong-Ho,Han, Jong-Woo,Park, In-Sung,Lee, Chul-Hee,Park, Sun-Young The Korean Neurosurgical Society 2007 Journal of Korean neurosurgical society Vol.42 No.4

Objective : The objective of this study is to investigate the safety, surgical efficacy, and advantages of a polyaxial screw-rod system for posterior occipitocervicothoracic arthrodesis. Methods : Charts and radiographs of 32 patients who underwent posterior cervical fixation between October 2004 and February 2006 were retrospectively reviewed. Posterior cervical polyaxial screw-rod fixation was applied on the cervical spine and/or upper thoracic spine. The surgical indication was fracture or dislocation in 18, C1-2 ligamentous injury with trauma in 5, atlantoaxial instability by rheumatoid arthritis (RA) or diffuse idiopathic skeletal hyperostosis (DISH) in 4, cervical spondylosis with myelopathy in 4, and spinal metastatic tumor in 1. The patients were followed up and evaluated based on their clinical status and radiographs at 1, 3, 6 months and 1 year after surgery. Results : A total of 189 screws were implanted in 32 patients. Fixation was carried out over an average of 3.3 spinal segment (range, 2 to 7). The mean follow-up interval was 20.2 months. This system allowed for screw placement in the occiput, C1 lateral mass, C2 pars, C3-7 lateral masses, as well as the lower cervical and upper thoracic pedicles. Satisfactory bony fusion and reduction were achieved and confirmed in postoperative flexion-extension lateral radiographs and computed tomography (CT) scans in all cases. Revision surgery was required in two cases due to deep wound infection. One case needed a skin graft due to necrotic change. There was one case of kyphotic change due to adjacent segmental degeneration. There were no other complications, such as cord or vertebral artery injury, cerebrospinal fluid leak, screw malposition or back-out, or implant failure, and there were no cases of postoperative radiculopathy due to foraminal stenosis. Conclusion : Posterior cervical stabilization with a polyaxial screw-rod system is a safe and reliable technique that appears to offer several advantages over existing methods. Further biomechanical testings and clinical experiences are needed in order to determine the true benefits of this procedure.
